Location SLMath: Eisenbud Auditorium Video -- Abstract We study behaviors of higher Mahler measure which is a generalization of classical Mahler measure. Apart from giving a broad overview of classical Mahler measure and higher Mahler measure, in this talk we shall show several new asymptotic properties of zeta Mahler measure (of a specific class of x-a) involving partitions of integers, the Rieman zeta function, the Dirichlet η-function and π.

02:45 PM - 03:15 PM		Selmer groups and class groups Kestutis Cesnavicius (Centre National de la Recherche Scientifique (CNRS))
Location SLMath: Eisenbud Auditorium Video -- Abstract Let A be an abelian variety over a number field K. If A has nontrivial (resp. full) K-rational p-torsion for a prime p, exploiting the fppf cohomological approach to Selmer groups, we obtain inequalities bounding the size of the p-Selmer group of A from below (resp. above) in terms of the size of the p-torsion subgroup of the ideal class group of K. When K varies in a family of field extensions, these inequalities relate the growth of Selmer groups to that of class groups; I will discuss such relations in several different settings.

Location SLMath: Eisenbud Auditorium Video -- Abstract We show how to realize the pro-p-Iwahori-Hecke algebra of SL_n as a subalgebra of the pro-p-Iwahori-Hecke algebra of GL_n. Using the interplay between these two algebras, we deduce a numerical Langlands correspondence between "packets" of Hecke modules and mod-p projective Galois representations.

02:45 PM - 03:15 PM		p-adic functoriality Judith Ludwig (Max-Planck-Institut für Mathematik)
Location SLMath: Eisenbud Auditorium Video -- Abstract I will explain a notion of p-adic functoriality. Roughly speaking the goal is to extend classical Langlands functoriality to a transfer of p-adic families of automorphic representations. As these p-adic families can be organized into mysterious geometric objects, so called eigenvarieties, one aims at giving this p-adic functoriality a geometric structure as well. I will explain what this means and if time permits discuss some results in the context of unitary groups. Supplements -- Show Detail

02:45 PM - 03:15 PM		On images of Galois representations associated to non-CM Hida families of modular forms Jaclyn Lang (Université de Paris XIII (Paris-Nord))
Location SLMath: Eisenbud Auditorium Video -- Abstract In the 1980s Ribet and Momose determined the image of Galois representations associated to non-CM classical modular forms in terms of conjugate self-twists of those modular forms. Recent work of Hida shows that Galois representations associated to non-CM Hida families have large image. We define conjugate self-twists in the context of Hida families and combine the above mentioned results to obtain a description of the images of Galois representations associated to Hida families. We will attempt to motivate and introduce the local Langlands conjecture for GL(2) in families proposed by Emerton and Helm, and discuss how the classical theory of zeta integrals and local constants works in this setting.

02:45 PM - 03:15 PM		Interpolating Periods Shrenik Shah (Institute for Defense Analyses (CCR-LJ))
Location SLMath: Eisenbud Auditorium Video -- Abstract We study the interpolation of Hodge-Tate and de Rham periods in families of Galois representations. Given a Galois representation on a coherent locally free sheaf over a reduced rigid space and a bounded range of weights, we obtain a stratification of this space by locally closed subvarieties where the Hodge-Tate and bounded de Rham periods (within this range) form locally free sheaves. At every thickened geometric point within one of the strata, we obtain a corresponding number of unbounded de Rham periods. If the number of interpolated de Rham periods is the number of fixed Hodge-Tate-Sen weights, we prove similar statements for non-reduced affinoid spaces. We also prove strong vanishing results for higher cohomology. These results encapsulate a robust theory of interpolation for Hodge-Tate and de Rham periods that simultaneously generalizes results of Berger-Colmez and Kisin. Supplements -- Show Detail
